Title: Data retransmission method/device
Inventor: MATSUKI HIDEO
IPC: H04L29/08
Filed: 1996-07-03
Abstract: PROBLEM TO BE SOLVED: To precisely recognize frames without confusing a modulo order by recognizing the transmission of the transmission frames through the use of a modulo identifier on an affirmative response number on a transmission side. SOLUTION: Not only the oldest frame number which is not recognized but also the affirmative response number 7 showing a reception result on the individual frames and the modulo identifier 8 on the pertinent number are provided to a feedback frame. On the transmission side, the transmission of the individual frames is recognized by containing not only the affirmative response numbers 7 which are successively transmitted but also the modulo identifier 8. The recognized frame is removed from a transmission object. Thus, transmission of the individual frames can be recognized without confusion by the same frame number appearing at every module. Wasteful transmission is avoided by skipping the frame which is previously recognized and transmission efficiency is improved.

IPC: G05B19/4063
Filed: 1987-07-30
Abstract: PURPOSE:To discriminate between normal discharge and abnormal discharge due to electric leak via a chip and the like by making a comparison between two types of discharge start reference voltage and voltage pulse voltage and detecting a voltage drop within the predetermined time after the output of a drive signal before discharge start. CONSTITUTION:Output voltage Vp is supplied as conversion reference voltage to D/A converters DAC1, DAC2, and conversion ratio data Sa and Sb are inputted thereto for output as discharge start and discharge reference voltages VA and VB to comparators OP1 and OP2. A voltage pulse is applied and a discharge gap signal Vo is detected. And this signal Vo is compared with the voltage VA via the comparator OP1. When the signal Vo is smaller, OUT1 as a drive signal before discharge start is outputted. When the signal Vo further drops, OUT2 is outputted via comparison with the voltage Vs in the comparator OP2. A timer TM1 is started with the signal OUT1 and outputs TW in the predetermined time. And the output OUT3 of a flip-flop circuit FF1 takes a logical product and sum with the signal OUT2, thereby outputting a normal discharge start signal OUT4 and an abnormal discharge start signal OUT5.

Filed: 1988-08-02
Abstract: PURPOSE:To delete the scattered X rays, the veil glare and other artifact by comparing the picture data on each picture element obtained for each frame with the comparison cut-off value having the prescribed relation with the minimum value of the frame. CONSTITUTION:The (n) frames of the original multislit assembly MSA picture data 102 are obtained by a picture input device 100 and stored in a picture memory 104.

Filed: 1983-10-14
Abstract: PURPOSE:To eliminate the need for an LPF, to attain a high speed response and also to obtain a high stability by controlling a voltage controlled oscillator (VCO) with three output levels of a phase comparator so as to bring a PLL circuit into the phase lock state. CONSTITUTION:An external input rectangular wave signal (a) is applied to a monostable multivibrator MM13 from a terminal 5 and the MM13 supplies a pulse (b) of a pulse width TW to a phase comparator PD12. The PD12 outputs a high level VH or a low level VL when the output of the MM13 is at a high level, and the PD12 outputs a middle level VM when the output is at a low level. The VCO3 oscillates three kinds of frequencies FL, FM and FH respectively in response to the three kinds of the output levels VL, VM and VH of the PD12. If there is a phase difference between an output signal of a frequency divider 4 and the external input rectangular wave signal, the ratio of a period TH when the PD12 outputs the VH in the TW to a period when the VL is outputted is changed, and the phase of the output signal of the frequency divider 4 is controlled so that the phases are made coincident. The output of the PD12 is the VM at periods other than the TW and the oscillated frequency of the VCO3 is an FM.
